A study led by sports scientists at
Dublin City University has found that the performance enhancing benefits
of caffeine are more apparent in athletes who do not drink
caffeine-rich drinks such as tea, coffee, and energy drinks on a daily
basis.
Researchers Dr Brendan Egan and Mark Evans from the DCU School of
Health and Human Performance examined the impact of caffeine, in the
form of caffeinated chewing gum, on the performance of 18 male team
sport athletes during a series of repeated sprints. The athletes
undertook 10 repeated sprints under conditions with and without two
sticks of the caffeinated gum, which is equivalent to two strong cups of
coffee.
They found that the caffeinated gum provided very little advantage to athletes whose bodies may have become desensitised to caffeine through a process called habituation, which occurs by having caffeine frequently.
However, the athletes who had a low habitual caffeine consumption maintained their performance in repeated sprint tests after ingesting a caffeinated chewing gum, while the performance of athletes who consumed the caffeine equivalent of three or more cups of coffee per day worsened over the course of the ten repeated sprints. This indicated that this second group did not benefit from caffeine as a performance aid.
Caffeine is regarded as one of the most popular performance enhancing supplements among athletes. Its benefits include improved muscle strength, mental alertness, as well as reducing the perception of effort during intense activity, therefore helping athletes to perform faster and longer.
The findings from the DCU-led study were published in the International Journal of Sport Nutrition and Exercise Metabolism. They recommended that athletes who consume caffeine on a regular basis should reduce their consumption in the lead-up to a big performance, if they want to receive the benefits of a caffeine supplement as a performance aid.
